Byron G. Rogers Federal Building: Denver, Colo.
Modernizing Denver’s 1960s-era Byron G. Rogers Federal Building capitalized on a decision made in 1850 by the original city planners to lay out the downtown streets at 45 degrees to the four cardinal points. Without considering the solar orientation, the design respected the street orientation and the result placed the main buildings facing southwest. While this is great for watching the sun set over the mountains, the building becomes a giant solar heat collector.
